Alexander Zverev appeared calm as a monk compared to the exuberance of his teenage opponent Carlos Alcaraz during their gruelling French Open quarterfinal on Tuesday and the German believes reining in his emotions was crucial to his win.
With the vast majority of the crowd at Court Philippe Chatrier rooting for the 19-year-old, who was on a 14-match winning streak, Zverev showed nerves of steel for the entire three hours and 18 minutes of the match.
